Letters Patent No. 109,298, dated November 15` 1870.

IMPROVEMENT IN COMBINED LATCHES AND LOCKS FOR SLlDlNG DOORS.

The Schedule referred to in these Letters Patent and making parto the same.

To all whom it 'may concern:

Be it known that I, J Aeon Carnon', of N ewlYork, in the county of New York and State of N ew York, haveinvented a newand useful Improvement in Locks; and I do hereby declare that the following is afnll and exact description of the same, reference being had to the accompayni-ng drawing and to the letters of' reference marked thereon.

This invention relates to locks for sliding doors, and consists, mainly, of an oiiset in the latch, by which all necessity for a blocking on the partition is avoided, all the features of' the lock being hereinafter fully set forth.

In the drawing Figure 1 is a plan view of the lock with the inner plate removed;

Figure 2 is a view partly in vertical section, showthe offset; and

Figure 3 is a top view ot' the door and partition locked in place.

The lock to which the improved catch is applied is formed with the usual face and end plate, fitted for attachment to the Iinside ot' the door, in the usual man- To this plate, at a., is pivoted the latch A, which is pressed down by a spring, b, suitably fixed to the plate, and pressingr against a spur on the latch a little above the'pivot.

The latch is further provided with arms c and o'.

The former projects vertically from the rear end, near thc pivot, and is so arranged that, when the latch is down, it shall pass over an opening in the plate, and hc capable of being pressed back by thc hand suh'iciently far to raise the latch. The other arm, c', rises from the other end of the latch, and serves, in conncction with other parts, to lock the latch.

These parts are D and E.' D is a bolt and springstop for the same, the former sliding on pins in the slots, and the latter pivoted at d, and pressed down by spring e, so that a small lug may fall into the notches e' e. The whole is arranged at proper distance above the key-hole, so that the key,` operated from the outside, may litt the stop and throw forward the holt over the end ofthe arm o', thus locking down the catch A'.

The other lock is a simple slide, which moves in proper guides, hei'ngoperated from the inside by a lng projecting through the plate, which, when thrown forward int-o the notch f, in the same manner, locks down the latch.

The latch is raised bya knob, theinner end of 'which has its bearingin asocket cast in the plate, land which is provided with 'the lugs g g. Through the plate is cut a hole, of proper dimensions, through which projects the offset Bf, (tigs. 3 and 4.) This projects suiiciently far to allow the catch or nosen h to come opposite the edge of the partition, in which is a suitably-recessed plate, K.

It will thus be seen, as clearly shown in lig. 3, that with this improved lock the door may shut by the partition' suiciently far, and lock securely. without any blocking on the partition.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

.The describedlock, with its latch A, stops D and E, spring arms c o', and offset on the latch, all constructed and opera-ting substantially as set forth.

This specih'cation signed and witnessed this 28th day of July, 1870.

JACOB CAPRON.
